www.intertec.info SL BLOCKTHERM DLA .. ADA Self-limiting Heater Plate 1 Application The electrically heated aluminium plate transfers the heat to transmitters or other instruments by conduction. This kind of freeze protection or temperature maintenance is easy, safe and economical. 2 Special Features  Energy-saving  Self-limiting, no limiter required  Space-saving  Large range of operating voltages 3 Description 6 A heating block SL BLOCKTHERM DLA in temperature class T3 or T4 (see data sheet HD660) is bolted onto a black anodized aluminium plate, ensuring efficient heat transfer. The solid plate may be drilled in any place to obtain good contact with the instruments to be heated. Optionally the heater plate can be supplied with a drill pattern suitable for mounting all standard transmitters (see point 8). 4 Technical Data Heating Power II 2 G/D EEx d IIC Temperature Class T4 EC Type Examination Certificate 110 to 265 V Nominal Power 50W Heating plate transmitter Protection Degree Connection Cable (in case of AM) IP 68 , NEMA 4X Silflex 3x1,5 mm2, Ø 8,5mm (Silflex 5x1,5 mm2, Ø 8,8mm) Material Aluminium, sea water proof; black anodized Also available to (CSA/NRTL/FM/UL).

Heat transfer through metal is more efficient than heat transfer through air. As the air surrounds the entire installation in the housing, it acts as an additional insulation. A black anodized finned profile on one side of the heater plate transforms the conduction heater into an additional convection heater. 5 DLA T4 ADA Ex-Types Operating Temperature Protection Degree Standard B80 ADA 110 to 265 V 50W 80W max. 200°C IP 68 Ordering Example: SL BLOCKTHERM DLA T3 ADA (Standard) SL BLOCKTHERM DLA T3 ADA BT AM (2 options) Page 1 / 2
